"This time four years ago Luke was starting at No12 for Leinster, he's had a fair bit of game time for me at 12 and we have confidence in him. He has played at No13 in the pre-World Cup matches and deserves his opportunity," Schmidt said.

Paul O'Connell will captain the side against the Canadians who are without their key player Tyler Ardron who is ruled out with injury.

The Ireland skipper will be partnered in the second-row by Iain Henderson whose form against France has been rewarded with a starting berth at the Millennium Stadium.

Dave Kearney is another whose form has been rewarded with a start on the right wing alongside his brother Rob.

"Going back two years, Dave Kearney was exceptional," he said. "Andrew Trimble too, but unfortunately he was right in the frame and picked up a second injury and the timeframes were tight. Dave was playing well and deserves an opportunity.

"Iain has played very, very well but Devin Toner has done a super job for us over last two years and there is going to be a real contest."

Although Ireland are heavy favourites to beat the Canadians, Schmidt has plenty of respect for them.

"Canada have guys who can turn a game around very quickly and have a number of guys who play Sevens and are used to a turnover attack. I know Jamie Cudmore well from my Clermont days and the power he brings," he said.
